Old school London mainstay Andipa Gallery is going to the streets and holding an exhibition of Banksy’s rare works on canvas. Guess it’s time the old money flexed it’s muscles and showcased some choice secondary market pieces from one of United Kingdom’s finest.

A veritable gem amongst gems is the ginormous “Are You Using That Chair?” measuring over 7 x 14′. This is by far the largest canvas that we’ve seen from Banksy. This remix of Edward Hopper’s 1942 masterpiece “Nighthawks” is an iconic example of why Sir Banksy is one of the freshest artistic minds around.
